It would be nice to have highlights/midtones/darks sliders for the Tone Curve along with its main chart. Dragging each node ensures precision of the module's application, however it makes using it very time consuming. Also, it takes a good grip of mouse with hand to control each node, which is sometimes impossible on uneven surfaces or with low precision mouse. This would also help to reduce strain in arms after work. Such sliders would also facilitate coarse adjustment within less time.

Which would do what?

In git master, you can already use keyboard arrows to move the currently highlighted (by mouse) point.

I suggest those to do the curve adjustment. Instead of the arrow keys that control certain node, those sliders would control areas of the curve - high, middle and low for highlights, midtones and dark tones respectively. Does that make sense?
